. To all whom it may concern: v`

Be it known'that I,- WILLIAM SKERMAN, a subject of the King v'of Great Britain, 'and a resident of Brisbane, Queensland, Australia, have invented a new and Improved Hose- Coupling, of which the following is a full, clear, and exact description.

This invention relates to a coupling for hose sectionsor other luid conductors, and it isuseful in any instance involving a sectional fluid conductor, notably, in railway air brakes,'and in the compressed air connections of rock drilling and analogous machines. i

`The invention com rises not only means I for effecting a releasab ehermetic connection between'the hose sgctions, but falso a novel means of automaticall opening and closing the hose sections ast ey are connected or disconnected. p I will give below'a description in speciiic terms of one exam le of my invention.

Reference is to e had to the .accompanying drawings forming a part of this specication. in which similar characters of'reference indicate corresponding parts in ail .thefviews Figure 1 is a planl view of the coupling' with its parts engaged; Fig. 2 is a'section fon the-line 2-2 of Fig. 3 3 is ashlee-levation of the coupling with its parts engaged;v ig. 3;I Fig. 5 isa detail perspective viy w of one vof Fig. 4 is a section on the line 4-4 or'4 the sections of the coupling; ano Fig. 6 is a side elevation showing the parts inthe act of connecting.

10 indicates the sections ofthe hose or l other tubular iluid conductor in connection \witl1 which my invention may be applied.

The hose sections are fastened by clips 11 to nipples 12 (see 6) formed on or secured to the respective sections of the couplingf To said clipsvi 1, springs 14 are secured these f n Springs extending inward and beingsui ably fastened to the after described.

f The coupling construction, and each comprisesa body 15 having therein a passage 16 communicating with the nipple 12. Said passagesv 16 open at the sides of the coupling sections, as shown pins 25, which'will be hereinmatching packing gaskets which are arranged one on each-'section to form arv hermetic, consectionsare duplicates in' 4formed at the lower portions of said mvities',

as indicated bythe broken lines in Figs. 2 and 3. 'In this manner the sections are remov- 'ably connected together, and to hold them yieldingly in this position, each section carries a spring 21, these springs overlap ing the opposite sections and causing the b1l s of the hooks 18 to be held firmly, yet yieldingly in en agement with the studs 20.

rossing the passage 16 of each section 15 isa valve seat 22, and in said seats are arranged plugs or other forms of valves 23 control ing the fluid movement through the passages 16." To the said plugs 23 slotted arms 24 are secured, and Within the slotsfof these arms are arranged respectively to play' the pins 25 of arms 26 carried one on each couping section, and the arm of one section ,heilig arranged to overlap the other section Aand to engage its pin with the slot of the arm 24 on said other'section. When the sections are engaged, the arms 24 stand transversely'to the sections as shown in Fig. 8, and when they are disengaged, the movement of the pins 25 through the slotted arms v24 will cause the arms 24 to approach parallelism with their coupling sections, thus imparting turning movement to the valves 23, and in this manner said valves may be made to open as thev coupling sections are moved into engagement, and to close as the coupling sections are moved out of engagement. The arrows in Fig. 6 indicate the relative movement of the sections in the actof engaging together, by means of which movement the arms 24 are thrown outward from eachother into the position shown in Fig. 3.

To disengage the sections, a reversal of this movement 1s necessary.' y

The spiral springs 14 act yieldingly to hold the sections engaged and to resist any opening action. These springs 14 are secnllcrlr at one end to the clips 11 and are provided with loo s at their other ends which are slipped on an. Voli" the pins 25 by hand, as and when required. Previously to uncoupling the sec-l tions thesprings 14 are slipped oil` the pins 25, and when coupling the sections the springs are stretched out and slipped on to the pins. Where the hose couplings are subject to forcible contact with any object, such as might hap en when used in connection with rock dril ing machines in mines, or for iire hose, the springs 1.4 serve a's a safe guard against any accidental un'coupling. `Various changes in the form, proportions and minor details of my invention may be resorted to at will without departing from the spirit and scope thereof, hence I consider myself entitled to all such variations as may lie within the intent of my claims.

Having thus described my invention, l claim as new and desire to secure by Letters Patent,- i

l. The combination of two coupling sections, hose sections respectively connected therewith, clips for joining ,the hose sections to the coupling sections, and springs connected to the clips and to the coupling s ections.

2. The combination of two coupling sections, hose sections, means for connecting the hose sections to the coupling sections, and springs connected to said. connecting means and to the coupling sections.

3. In a hose coupling, the-combination of two coupling sections-each having a passage therein, the said passage/S registering with ,each other when the sections are engaged,

each coupling section having a hook member adapted to enter a cavity in the other sec tion, the bills of the hooks engaging studs formed 'at the lower portions of said cavities to removably .holdthe sections together, each coupling section also' having a longitudinally projecting arm extending beyond the hook member and adapted to overla the other section, a valve mounted in eaci section and commanding the passage thereof, and an arm connected to each valve,l the last named arm of one coupling section being adapted to engage a part of' the first named arm of the other section, whereby automatically to operate the valve, and springs supported at one end and connected at the other end with the said longitudinally projected arms.

4. In a hose coupling, the combination of two coupling sections each having a passage therein, and the passages registering with each other when the sections are engaged., each coupling section having a hook member adapted to enter a cavity in the other section, the bills of the hooks engaging studs in said cavity to removably hold the sections together, each coupling section also having a longitudinally projected arm extending bee yond the said hook member and adapted to overhang the other section, a valve mounted in each section and commanding the passage thereof, and an arm connected to each valve,

`the last named arm of one. coupling section being adapted to engage a part of the iii-st named arm of the other section whereby automatically to operate the valve, the second named arms being longitudimllly slotted and the iirst named arms having' laterally disposed pins at their ends received in the slots.

5. In a hose coupling, the combination ol' two coupling sections each having a passage therein, and the passages registering with each other when the sections are engaged for the purpose specified, and each coupling scc tion also having a longitudinally projected arm adapted to overhang the other section, a valve mounted in each section and commanding the passage thereof, :in alm con nected to eac". alvc, the last nam'eftai'ms of one coupling section being adapted to engage a part of the first named arm ol the other section whereby automatically to operate the valve, clips adapted tol connect the hose sections with the coupling sections, and 'sprin connected to the clips and to the iirst named arms of the opposite coupling sections respectively.

6. In a hose coupling the combination o two coupling sections, a rocking valve commanding each section, an arm connected with each valve and swinging with the same to open and close the valve, a connection bc- .tween each of said arms and the other cou iling section to operate the valve upon t ic `relative movement of the coupling sections,

clips for connecting the hose sections with the coupling sections, and springs connected to the clips and -to the coupling sections.

In testimony whereof l have signed my name to this specification in the presence of two subscribing witnesses.
